OLIVER SLAGLE, OF LEAVENWORTH, KANSAS, ASSIGNOR OF ONE-HALF TO ARTHUR M.

MARDEN, OF LEAVENWORTH, KANSAS.

THREAD-CUTTER.

Specification of Letters Patent.

Patented Sept. 24, 1907.

To all whom it may concern:

Be it known that I, OLIVER SLAGLE, a citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certain new and useful Improvements inThread-Outters, of which the following is a specification.

The present invention relates to certain new and useful improvements inthe construction of that type of thread cutters which are designed to beemployed in connection with a spool, one of the objects of the inventionbeing to provide a device of this character which not only forms a meanswhereby the thread can be readily severed, but also constitutes a clampfor engaging the end of the thread and thereby preventing the threadfrom unwinding from the spool.

The invention also aims to so design the thread cutter that it can beapplied to spools of various sizes, and so that it can be cheaplymanufactured by stamping the same from sheets of spring material.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the de tails of construction and the means foreffecting the result, reference is to be had to the followingdescription and accompanying drawings, in which:

Figure l is a perspective view of a spool of thread having the improvedthread cutting attachment applied' thereto. Fig. 2 is a top plan view ofthe same. Fig. 3 is a side elevation of the thread cutting devicedetached.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The invention is shown as applied to a spool 1 of the usualconstruction, the body portion of the spool being provided with thelongitudinally disposed opening 2. Fitting removably within one end ofthe opening 2 is the plug 3 upon which the thread cutter proper ismounted. In the specific construction of the thread cutting device itwill be observed that the same comprises an elongated plate 4 which isadjustably connected to one end of the plug 3 and has one end thereofcontracted in width toward the extremity thereof which is provided withthe downwardly extending arm 5 designed to engage the rim of the spooland form a stop for the thread as will be hereinafter described. Theadjustable connection between the plate 4 and plug 3 is accomplished inthe present instance by providing the plate with a longitudinallydisposed slot 6 through which the headed fastening member or screw 7extends by means of which the plate is secured to the plug; Projectinglaterally from one side of the plate 4 and bearing against the head ofthe spool is the blade 8 which has one of its edges sharpened to formthe cutting edge 9, the said cutting edge facing the opposite end of theplate 4 to that provided with the arm 5.

In applying the thread cutter to a spool the plug 3 is inserted in theopening 2 extending therethrough and the plate 4 moved until the arm 5is brought into engagement with the head of the spool. The screw 7 isthen tightened in order to securely clamp the plate 4 in its adjustedposition. After the desired length of thread has been unwound from thespool, the thread is passed around the arm 5 and drawn under the blade8, when it can be quickly severed by drawing it rearwardly and inengagement with the cutting edge 9.

It will be observed however that after the thread has been severed theend of the thread upon the spool is clamped between the blade 8 and thehead of the spool and the thread carried by the spool thereby preventedfrom being accidentally unwound. When it is desired to withdraw anotherlength of thread the desired result can be readily accomplished bygrasping that portion 10 of the thread extending diagonally acrosstheplate 4, and then unwinding the required length in the usual manner.

Having thus described the invention, what is claimed as new is:

1. In a thread cutting attachment for spools, the combination of a plugfitted within the opening through the spool, a plate carried by theplug, an arm projecting from one end of the plate and designed toengagean edge of the spool, and a laterally projecting blade carried bythe body portion of the plate and having a spring engagement with theend of the spool for retaining the thread.

2. In a thread cutting attachment for spools, the combination of a plugfitted within the opening through the spool, a plate carried by .theplug, an integral arm extending downwardly from one end of the plate anddesigned to engage an edge of the spool, and an integral bladeprojecting laterally from the body portion of the plate, the cuttingedge of the blade facing the opposite end of the plate to that providedwith the before mentioned downwardly extending arm.

3. A thread cutting attachment for spools comprising a plug fittedwithin the opening through the spool, an

plug fitted within the opening through the spool, an elongated platestamped from spring material and provided with a longitudinally disposedslot, a fastening member extending through the slot and adjustablyconnecting the plate to the plug, an integral arm extending downwardly 5from one end of the plate and engaging an edge of the 'spool, and anintegral blade projecting laterally from the plate, the cutting edge ofthe blade facing the opposite end of the plate to that provided with thebefore mentioned arm and the said blade serving the double function ofsevering the thread and of clamping the end thereof 10 against the headof the spool.

In testimony whereof I aflix my signature in presence of two witnesses.
